[catalogued under 27. Natural Reality / D. Time / 3. Parts of Time / d. Measuring time]

It is possible that there is no uniform motion by which time may have an exact measure. All motions can be accelerated and retarded, but the flow of absolute time cannot be changed.

Gist of Idea

If there is no uniform motion, we cannot exactly measure time
